Thermocouple. A thermocouple is a kind of temperature sensor.


Unlike semiconductor temperature sensors such as the TMP36 , thermocouples have no electronics inside them, they are simply made by welding together two metal wires. Because of a physical effect of two joined metals, there is a slight but measurable voltage across the wires that increases with temperature. The type of metals used affect the voltage range, cost and sensitivity, which is why we have a few different kinds of thermocouples. The main improvement of using a thermocouple over a semiconductor sensor or thermistor is that the temperature range is very much increased. Controlling an Arduino with an iPhone. Skill Level: Beginner by Pete-O | November 30, 2009 | 72 comments You can download the Source Code here.

Controlling an Arduino with an iPhone

How it works: In this tutorial you will learn how to communicate between the iPhone/iTouch app TouchOSC via a WiFi network to a Processing sketch displaying graphics and finally to control an Arduino board to light up an LED. TouchOSC is just one of many iPhone/iTouch apps that can send Open Sound Control signals. Xoscillo - A software oscilloscope that acquires data using an arduino or a parallax (more platforms to come).

About This is a multiplatform software oscilloscope and logical analyzer.

It supports arduino(with custom firmware) and a Parallax USB oscilloscope. More platforms to come. Turn Your Arduino Into an ISP. There are a few instances in which it is neccesary to program microcontrollers without a bootloader.

Turn Your Arduino Into an ISP

For example, if have run out of storage on a chip you can get an additional 2KB when you program without a bootloader. Another example, the one I will show you how to do, is to program chips that have no serial capabilities and therefore cannot use a bootloader. Arduino & Freeduino Knowledge. Breadboard Sanguino. Okay, so you want a Sanguino but Zach's Sanguino is too expensive ;-> Or too red ;-> Or you just have to have it NOW ;-> And you just used up the last of your solder so a strip board is out.

Breadboard Sanguino

What are you to do … bread board Sanguino. Of course, nothing in life is free. Freeduino Knowledge Base. Adafruit. Arduino Blog. Using an Arduino + Ethernet Shield to Update a ThingSpeak Channel. This tutorial demonstrates how to use the Arduino to read in the analog input and update a ThingSpeak Channel by sending an HTTP POST via the Arduino Ethernet Shield or the Arduino Ethernet (all-in-one).

Using an Arduino + Ethernet Shield to Update a ThingSpeak Channel

The analog input can be the output of a sensor, like a light sensor or temperature sensor. ThingSpeak Client Arduino Sketch This Arduino sketch takes the value of Analog Pin 0 and updates Field 1 of a ThingSpeak Channel using the ThingSpeak API.
